IMPROVEMENT IN GANG-#FLOWS l MMM The Schedule referred to in theseLetters `Patent: and making part o f the same.

To all whom it may concern.-

Beit known that I, J.` XV. Lewis, of Oregon City, in the county ofClackamas, and State of Oregon, have invented a new and usefulLmprovement in Gangfollowing is a full, clear, and exact description ofthe saine, reference being had to the accompanying drawings, forming apart of this specication.

Thisiinvention consists in the novel construction of a gan g-xplow,whereby ellicien'cy, durability, and cheap- Figure 1, in theaccompanying drawings, represents a, longitudinal section ofa gang-plow,constructed according to my invention; and

Figure 2, a pian view of the same.

Figure 3 represents a transversey sectional view of the axle, with onewheel attached, showing a device employed in effectingverticafadustmentef the axle",- and Figure 4 represents right anglesthereto.

Similar letters of reference. indicate corresponding parts in theseveral figures.

A is an axle, mounted upon two wheels, B B, and

another view of fig. 3, taken at provided with a tongue, G,substantially as other gangf plows.

Erected over' said axleA is the ordinary drivers seat D.

Within the frame which supports this seat, is provided a verticalguide-way or slot, a, within which is arranged, to slide up and down, aconnecting-bolt, b, which passes transversely and in a horizontaldirection through the front ends of two beams, E E. Said beamsarc hungto and dragged behind the above-described currele, by means of the saidconnection of the bolt b with the slot or guideway d.

The beams E E are provided with are connected to each other by anysuitable means, so as to leare sufeient space between them forY theproper separation of the plows. A

The rear portion ofthe tongue O is divided or bi-` pronged, and withsuliicient space between said prongs for reception cfa level', G.

Said lever G is horizontally arranged,rand pivoted between the prongs ofthe tongue, at a point, c, in

Vfront ofthe axle, and with its rearyend in position for operating igainstor under a friction-roller, e, attached between the. beams E E.

4 Said friction-roller c is located atasuitable distance behind theconnecting-holte, for obtaining the most satislirctory results inlraising the said beams and disengaging the plows from the ground, say,at a point,

9:, in the drawings.

lhe front portion of this lever G carries a frictionroller, g, and is,furthermore, divided or lli-pronged, for reception, behind the saidfriction-roller g, of a curved arm, f.

Said curved arm f is attached to the lower` extremplows,-Ii F, and v ityof a vertically-arranged .hand-lever, H, so as to act against the rearand upper sides of the said frictionroller g, by the backward movementofthe said hand- ,lever, while a ldili'erent but similarly-acting arm,Lf', also attached to the lower extremity of the same lever, comes incontact with the said frietion-roller from the front, and passes underthe saine, so as to act against the front and under sides of the saidroller bythe forward movement of the lever,so that `the forward andbackward movements oi said hand-lever will cause the oscillation of saidlever,'thereby raising aud lowering the beams E,-.tog'ether with theplows F.

`Assistance may be rendered the plows to enter the ground more readily,when desirable, by means of a diction-roller, c', which :is suspended ina swinging frame, immediately below the roller e, and against which thelower side of the rear end'of the lever G'v acts, by'tlie'frivardmovement ofth'e flan'ddever'H;

The axleA is not supplied with rigidly-attached i arms or spindles forthe wheels,- as isusually the case, but issu'pplied with adjustable armsor spindles, o o, whereby a means 'of vertical -adlustment is given 'tothe said axle, for the purpose of varying, when desirable, the depth ofpenetration ofthe plows.

Said vertical adjustment is eectcd by means of a vertical slider, an,secured upon the shoulderofthc arm o, and fitted toslide between lips n,forming a Vsuitable guideway upon the extremity of t-he axle A, so thatthe sliding of the parts will cause the raising or lowering of the saidarm o, relatively to the axle A, or a similar movement of the `said axlerelatively tothe arm, when said arm is being supported upon ythe wheel.l

, Said slider m is provided with a rectangular forward extension', p,together with an upwardly-curved for ward extension, p

' lo the forward .extremity of the said rectangular fbrward extension p,is pivoted, through its lower cxtreinity, a vertical or nearly verticalhand-lever;, fr, so as thereby to allow the said hand-lever a forwardand backward movement, while it is guided, atthe same timein said,movements, by a lip, s, secured thereon, and fitting over theupwardly-curved formation p' of the said slider m.

The said hand-lever ris provided, at its lower extremity, with arectangular'rearward extension or arm, fr. Said arm r is oi' acorresponding length with tbe rectangular forward extension p of theslider fm, and is connected with the upper side of the extremity of theaxle A, orl to the upper part of the guideway n, by means of ahingedlink, or short toggle-lever, q, so that thev forward or backwardmovement of the .handlever lr will cause the raising or lowering of theaxle.

` rl.he axle is retained at its dili'erent degrees of ad` justment,which may be thus given to it, by means.

of a spring locking-lever, V,arranged on the outside of the hand-leverlr, and lengthwise thereof.

Said locking-lever V is pivoted upon the said hand,

lever fr, by a pin passing through it and through ears, u, upon the saidhand-lever, near its central portion; and it is provided at its lowerextremity with a rectangular inward projection or locking-pin, V, whichpasses through an opening in the lip s, and into any one of a series ofholes, t', near the edge of the curved extension p' of the slider m.

For raising or loweri-ng the axle, and thereby varyf ing the depth ofpenetration ofthe plows in the ground,

the upper extremities of the two levers o' and V, which are arrangedside by side, are taken at the same time, and so grasped by the hand asto force the lockinglever V towards the hand-lever r, thereby unlockingthe said hand-lever bythe withdrawal of the locking` pin Vfrom the hole1', in which it may be locked,`

when, by a forward or backward movement of said l hand-lever, the axlemay be raised or lowered atpleas-'` ure. By relaxing the grasp,'aftersaidadjustment has been eli'ected, the locking-lever V is forced outwardby the actionof a spring, z, forcing the locking-piu V" into any one ot'the holes "i which may be oppositeto it, thereby locking the hand-leverll', and retaining the axle at said adjustment. f i 1 The' applicationof a device, similar to the one above described, is necessary 'at eachend Aof'the axle, and

operated by both hands simultaneously, to insure a uniform adjustment ofboth extremities of the said axle. l

la k are cutters, so secured to the dat side of the plows F F as topresent a cutting-front to said plows,

' for the separating or cutting asunderof roots, or other impediments,which may li'e in the line of theircourse, and are or may be screwed, orbolted, or otherwise secured Ato the plows, so as to be easily removedfor any desirable purpose.

These cutters 7c k are. provided with curvilinearlyformed edges, formore readilycutting or separat-ing.

'said roots, or other obstaclesrand also, with their .upper extremitiesof a laterally-curved formation to outline.

Said 'raised condition of the front ends of the said beams places theplows in a position for'cuttingvtheir way out of the ground, and afurther backward move ment of the said lever H will cause the points ofthe plows to be raised above Athe surface ofthe ground.

The position of the beams E, while in thisI condition, may be reversedbythe pressing of the foot. of the driver upon a horizontally andforwardly-projecting foot-lever, I, attached to the forward ends ofthebeams E. Said pressing of the foot upon the lever I causes the beamsto turn upon the friction-roll`er eas a fulcrnm', thereby directing thepoints of the plows downward, so as to be in position for entering theground upon the'forward movement ofthe said lever.

What'Iclaim as my invention, and desire to have secured by LettersPatent, is-f 1. The l1oistinglever.G of a gang-plow, arranged foroperation, in connection with the hand'lever H, for raising theplows,substantially as herein described.

2. The curved extremities or arms f f', in combination with thehand-leverHand hoistinglever G, substantially as and for the purposeherein set forth.

3'. The swinging flame, andv roller e', in combination with the beams E,aud level-2 G, substantially as and for the purpose herein set forth. y
